RADIATOR FOR LIQUID-COOLING SYSTEMS;

v To all whom t may concern:

Be it known that we, DoiiiuiciifDiLEo and NICOLA Lann-citizens of" the UnitedA States, residing at Utica, in the county of Oneida and State of New York, have invented' new and useful Improvements in- Radiators for Liquid- Cooling Systems, of'- which the followingV is a specification.

This invention 'relates to radiators` for liquid-cooling systems, the main object of the inventionl being to produce a yradiator which may be economically repaired' in case a leak springs therein in one of the liquid conduitsortubes, thev construction of the radiator being such thatthe radiation plates or flanges may be readily disconnected in any desired number' frointhe liquid tubes, thereby exposing a suflicient portion of one or more tubes to enable the leak to be re-l paired and stopped. This enables the. ra-

' diator to be repaired by an unskilled workman and at almost any place such as a smallvillage or even on the road, a solderin iron and a smallarnountof solder being al that is required in addition to some kind of a burner or lamp for heating the soldering iron.

With the above and other objects in view, the invention consists in thenovel construction, combination and arrangement'iof parts, as herein described, illustrated and claimed. In the accompanying; drawings, Figure l is a front elevation of' a radiatorembodying the present invention, the outside casing being partly broken away. Fig. 2 is a'hori vz'ontal cross section through the same illustrating by dotted lines the manner of withdrawing' the radiation plates.' Fig. 3 is a yvertical'crosssectionthrough a portion of the radiator on an enlarged scale. Fig; 1l is a Jfragmentary vertical section through the` radiator showing the provision of a space` for one of the clamping bolts or screws. nFig. 5 is anv enlarged'iragmentary vertical section showing the' disposition of several radiation plates in relation to one or more oflthe liquid tubes. Fig. -6 ,is a

detail perspective' view' showing one of the radiation plates. Fig. 77 is a similar view of` another adjoining radiation plate.

In the main the radiator resembles that l.

now in common use on automobiles, motor trucks and. the like, the same being shown as comprising the upper manifold or Water chamber l, the lower water chamber .or manifold 2, and water pipes 3l connected at Specification of Letters Patent.

their upper and lower .ends respectively to the manifolds 1 and 2 so as to conduct the water from one manifold to the other.`A

`Asshownin Fig. 2, the tubes 3 are all arranged parallel -to each other -and are fur? ther arrangedin rows or series, said` rows or series *being` parallel to eachother.. Any desired number of rows of pipes may, of course, be employed 'in accordance the any desired number of pipes` may `be-"contained in each row, the essential feature of 'the invention being that said pipes are ar ranged inv parallel'series substantially as shown in Fig. 2.

, ln connection with the pipes arranged as 'hereinabove set forth, we employ two series,

A and B, of radiation plates or, as they are sometimes termed, radiation ns orlianges.

they are removed from the lradiator in the saine. manner. Preferabl each, plate is in the form of an elongated rectangular thin sheet of metal and the slots 4t are formed by a suitable punchingpress'wliich simul'- taneously produces all of the slots in each radiation plate. Flanges 5 and 6 extendingv longitudinally of the side edges of the slots are pressed downwardly and said flanges converge toward each other as shown in the drawings. Therefore, when' the radiation'.

plate is pushed inwardly to its final posi tion, the flanges 5 and 6 engage and press frictionally and with a spring action against the pipesat points diametrically opigiosite. thereof. This provides for heat radiating contact between the radiation plates and the pipes and also avoids any ossibility of said plates rattling'or jarring cose.

C designates an outer shell or casingwhich is adaptedv 'to slide over the structure hereinaboye particularly described and as .f

indicated in Figs. l and, said casing C be ingpreferably removable by lifting the same in a vertical direction off the top of the structure hereinabove described. In order co-l e5 f size and capacity of the radiator andn lso '75 The shape4 ofeach one 'of these radiation plates is illustrated in Figs. 2, 5 'and '6 wherein it will be observed that said plate ico to hol all of the parts securely together,

we vemp oy a. suitable -number of screws or K bolts 7 which are insertedthrough holes in :the outer casing or shell C as shown in F 1g.

1 'and which pass between certain radiation plates adjacent toV the upright side frame I 'Q members Srof the radiator which connect the l top and bottom kmanifolds 1 and 2 and ,.5 which, incidentally, are provided `with offl0 standing' arms 9 by means of whichthe radiator may be supported on apart of the -rame of themachine. In order to provide rsuliieient space for each of the bolts 7, one ofthe platespas shown in Fig; 4, has its opother downwardly to form` terminal. spacthere are strips or' plates 11 through which posite end portions splilts-orpdivided, one part thereof being-turned upwardly and the ing flanges or members'lO' fBy reference to Fig. '4l it will be observedl that every other plate is provided-at the ends or the extremities thereof with upwardly and downwardly 4inclined or obliquely disposed spacing lianges'or members, the same. bearing against Y Vtheother plates so as to hold all ol"kv the plates in spaced relation to each other while at the saine time leaving spaces for the clamp- -f then llocates the` leakA by close and thereafter removes a `suflcilent number of radiation plates t 'expose that portionofv the pipe 3 to enable the hole or leak thereinito` be soldered. If oneofthe forward pipes is alfected, itis not necessary observation K to remove any of the plates of the rear .series A and conversely, if one of the pipes,A`

3 of the rear rows.` is affected. After the leak has been soldered `or otherwise repaired, the 'removed 'radiation plates are reinserted and the easing C replacediand secured.

What Weclaim is f f .In a radiatorforliquid cooling systems,v the combinationof 'parallel liquid tubes arranged in parallel series, and yradiator plates toY extending at right angles to said tubes and in parallel and'spaced relation to eachothenl said` radiator plates bemgforlned with tube lrecelying slots each open at one end permitting L'sai'dvplates 4to slide into and ont of p0-` i sition and normal relation to said tubes, said radiation plates being provided at opposite sides ofeach slot I. with downwardly conierging. yieldable llanges, bearing against said tubes, alternate plates being formed 'with 4spacing lianges which are 'normally disposed' at oblique' angles `to the bodies vof the plates,
